SB2G-M3/52T

Single Diodes Overview

The SB2G-M3/52T is a standard rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum average forward rectified current of 2 A and a repetitive peak reverse voltage of 400 V. The device utilizes the GPP (Glass Passivated Planar) technology and is housed in a DO-214AA (SMB) surface-mount package. Key electrical characteristics include a maximum DC blocking voltage of 400 V, a forward voltage drop of 1.1 V at 2 A, and a non-repetitive peak forward surge current rating of 60 A. The component supports a junction temperature range from -55°C to +175°C.

Single Diodes Feature Summary

• Utilizes glass passivated planar die technology for enhanced reliability and stability under thermal stress.
• Features a low-profile surface-mount SMB (DO-214AA) package designed for automated assembly processes.
• Provides high thermal performance with an extended operating junction temperature range up to 175°C.

Single Diodes Applications

• General-purpose rectification in AC-to-DC power supply circuits
• Reverse polarity protection in electronic systems
• Freewheeling applications in inductive load switching

Single Diodes Procurement Notes

Verify the specific ordering suffix against official Vishay documentation to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives and REACH regulations as stated in the manufacturer's datasheet. Confirm that the requested quantity aligns with standard factory packaging requirements to avoid handling discrepancies during procurement.

Single Diodes Selection Notes

Select this component when a 400 V reverse voltage rating and 2 A continuous current capacity are required in a compact surface-mount form factor. The SMB package offers a balance between current handling capability and board space efficiency compared to smaller SOD packages. Consider the 175°C junction temperature limit for high-temperature environments where standard 150°C rated devices may be insufficient.

Single Diodes Part Context

This part belongs to the SB2 series of standard rectifiers from Vishay, which provides various voltage ratings within the same physical footprint. The M3 suffix indicates lead-free construction compliant with EU Directive 2015/863. The /52T designation typically specifies the reel packaging configuration used for high-volume surface-mount production lines.

Single Diodes Replacement Considerations

Direct replacements must match the 2 A current rating, 400 V reverse voltage, and DO-214AA (SMB) package dimensions. Verify that alternative manufacturers offer equivalent forward voltage drops and reverse leakage currents to ensure circuit compatibility without redesign.
